Determination of Biological Activity Embodiment 8 Determination of Control Effect on Plant Bacterial Diseases

The compounds of the present invention are used to determine the control effect on various plant bacterial diseases. For different bacterial diseases, the test procedures are as follows:

Melon bacterial fruit blotch: the compound to be tested is dissolved with a small amount of N,N dimethylformamide and diluted with water to the required concentration. The pathogenic bacteria cultured to a stable growth stage is evenly mixed with a quantitative compound solution; the germinated melon seeds are soaked in the mixed solution of a bacteria solution and the compound for half an hour; then, the seeds are sown in an earthworm soil culture cup and put into a greenhouse for moisturizing cultivation for two weeks generally; and the control effect is investigated after full onset of diseases through control.

Soft rot of Chinese cabbage: 2 cm of square Chinese cabbage leaf is cut and placed in a glass petri dish lined with double-layer filter paper. A compound dissolved in N,N dimethylformamide and diluted with water to a required concentration is sprayed onto the surface of the Chinese cabbage leaf. After the medicinal liquid on the surface of the Chinese cabbage leaf is dried in a fume hood, the surface of the Chinese cabbage leaf is acupunctured by using an inoculating needle to cause a wound. 5 ml of soft rot bacteria of Chinese cabbage cultured to a stable growth period is added to the wound for inoculation. Finally, the test materials are placed in an incubator and cultured for 48 hours in the dark; and the control effect is investigated after full onset of diseases through control.

Test results are as follows:

At 400 mg/L, compounds 4, 5, 6, 20, 22, 23, 34, 36, 45, 47, 65, 74, 86, 87, 95, 97, 99, 104, 117, 118, 119, 123, 134, 179, 228, 253, 361, 366 and 367 have 100% control effects on soft rot of Chinese cabbage.

Embodiment 9 Determination of Control Effect on Plant Fungal Diseases

An in vivo pot determination method was adopted, i.e., a sample of the compound to be tested was dissolved with a small amount of solvent (the type of the solvent may be, for example, acetone, methanol and DMF, and selected according to the capability to dissolve the sample; the volume ratio of the amount of the solvent to the amount of sprayed solution is equal to or less than 0.05), diluted with water containing 0.1% Tween 80 and formulated into a required concentration of solution to be tested. Foliar spray treatment was carried out with the compounds of the present invention at the designed concentrations. A blank control with clear water spray was set and repeated for three times. Disease inoculation was carried out on the second day after the treatment. After inoculation, the plants were placed in a phytotron for moisturizing cultivation (temperature: 25° C. on day, 20° C. at night, relative humidity 95-99%). After culturing the test material for 24 hours, the plants were transferred to a greenhouse for cultivation, and the plants that did not require moisturizing cultivation were directly inoculated and cultivated in the greenhouse. After the control was fully diseased (generally one week), the control effects of the compounds were evaluated. For the result survey, A Manual of Assessment Keys for Plant Diseases compiled by American Phytopathological Society can be referred to, which uses 100-0 for representation. “100” level represents no disease and “0” level represents the most severe disease degree.
